Application led December 20, 1917. Serial No; 208,129'.

To all whom it may concern:

Be it known that I, ERNEs'r C. HEAD, a citizen ot' the United States of America, and a resident of Van Wert, Ohio, have invented a new and useful Improvement in Control Mechanism, which invention is fully. set forth in the following specification.

This invention relates to control mechanism and, while capable of a wide variety of uses, has es ecial utility when applied to the control o the feed and rapid-traverse mechanism of a machine tool.

An object of this invention is to rovide improved control mechanism for a p urality of operative elements whereby said elements may be actuated selectively from a common point of control.

A further object of this invention 1s to provide three or more operative elements with control mechanism whereby said elements may be actuated selectivel by the operation of a single control mem r operativcly related to all of said elements in its neutral position.

A still further object of this invention is to provide a plurality of elements each of which has a non-operative position and one or more operative positions with a sin le control device of improved construction whereby said elements may be selectively actuated to cause the same to assume any of said positions.

Yet another object of this invention 1s to provide translating mechanism with control mechanism whereby the speed and path of movement of a translatable member may be selectively controlled by the operation of a sinle c introl member.

i till another object of this invention is to provide a machine tool with a single control device for predetermining the speed and direction of movement of the tool holder both vertically and horizontally. y

Other objects relate to the provision of a control mechanism of the type indicated that is simple in construction, ilexible iii use, efficient in operation, and easy of manipulation.

Stated broadly, the invention, from one point of view, comprises a plurality of open ative elementsysbown as clutches, and control mechanism operatively related to all of said elements in its neutral position and adapted to actuate the same, said control .mechanism being so constructed as to enable the selective actuation of said elements by the operation of a single control member. From. another point of view, it comprises, in combination with a translatable element, mechanism for translating said element in a plurality of paths, mechanism for determining Whether said translatory movement shall be fast or slow, and a sinffle control device operatively related to said mechanisms for selectively predeterminin the speed and path of movement of said element. Said control device, in its referred embodiment, comprises a lever fu crumed for universal movement, an index plate provided with slots for guiding 'said `lever to any one of its positions for causing actuation of the controlled elements, and operative connections to said controlled elements, certain of said elements, in the embodiment shown, being actuated only by a movement of said lever different from that required for the actuation of other of said elements. When the connections between said lever and the elements to be controlled are mechanical, said connections may, and preferably do, comprise, as shown, a plurality of movable members positioned to be operated b said lever, means whereby movement o. said lever is transmitted to but one of said members, and means, constituting an interlock between said members, whereby movement of the other of said members is prevented.

The invention is capable of receiving a variety of mechanical expressions, one of which is shown on the accompanying drawings, but it is to be expressly understood that the drawings are for the 'purpose of illustration only, and are not to be construed as a definition of the limits of the invention` reference being had to the appended claims fo'r that purpose.

In said drawingS,-

Fig. 2 is a vertical transverse section on line 2-2 of Fig`.'1;

Figs. 3, 4 and 5 are details of members operated by the control lever; 4

Fig. 6-is an assembly view, partly 1n sectional elevation, showing certain elements of the invention in their proper relation to each other;

looking downward n'to the same from the direction of the line 7-7 in Fig. 6;

Fig. 8 is a front elevation of one slde or half of a vertical boring and turning mill equipped with the improved control mechamsm Fig. 9 is a side elevation of such mill;

Fi 10 is a face view of the case cover and index plate; and

Fig. 11 is a fragmentary vertical section of the saddle and cross-rail.

Referring in detail to said drawings, wherein the same characters of reference are applied to the same parts in the diferent vlews, the invention is shownas applied to the control of clutch"mechanismin-thegear trains for causing the feed and rapld traverse movements of thetool-holder of a vertical boring and turning mill. But 1t. is to be expressly understood that the inventlon is not restricted to use with clutches nor to use.

in this particular type of machine tooL for it is capable of use, not only with other gear elements and in other machine tools, but wherever it is desired that a plurality of ele. ments to be controlled shall be selectively actuated from a single .,point.

The mill is shown as provided with the usual cross-rail 1, upon which 1s mounted the usual saddle .2, a feed screw 3 enga ed by a nut 4 (see Fig. 11) rigidly secure to the back of said saddle bein provided to cause the travelof said sadd e onr said rail in horizontal directions. VCarried by said 85. saddle is a vertically movable ram 5 fed in vertical directions by the coaction of a rack 6, upon the side of said ram and a pinion 7 mounted upon a shaft 8, suitably journaled in said saddle and rotated by a worm wheel 9, which worm wheel meshes with a Worm splined on yfeed rod 10. As the above mech nism is of known construction, further detailed explanation is deemed unnecessary,

In the `operation of a boring "mill, it is desirable that the feed of the saddle 2 shall cause movement of said saddle Veither outwardly from the center of the table orinwardly toward the center of the table. It is also desirable that the feed ofthe ram 5 shall cause movement of the ram either upwardl or downwardl Furthermore, it is desire le that in addition to such feed movements, which Vare comparativ Y slow, there be movements corresponding creto which may be made with rapidity, and which rapid movements are usually termed the rapid traverse of the saddle or of the ram respectively, being generally em loyed when resetting these e ements, or w en sim ly moving them from one position to another with the tool out of operative engagement with the work. Therefore` it will be seen that mechanism should 'be provided to effect the following movements of the saddle: 1st, feed to the right; 2d, feed to the left; 3d, rapid traverse to the right; 4th rapid traverse to the left; and also to eiizect the following movements of the ram: 5th, upward feed; 6th, downward feed; 7th, upward rapid traverse; and 8th downward rapid traverse. Furthermore, it 1s obviously desirable that the direction and speed of such movements of the saddle and ram should be controlled from a single point. The control device of the present invention is adapted to selectively eilect any of the eight movements above enumerated, b the manipulation of a single member, pre erably manually operate Referring to Fig. 6, 11 designates a feed box containing a train of gearing throu h which the drive of the feed screw 3` and t e feed rod 10 is transmitted. Such train of gearing may be of any suitable construction Such, for example, as disclosed and claimed in my application Serial No. 201,245 filed Novem er 10, 1917. Driven by the gearing within said feed box 11 in the form shown "is a vertical shaft 12, to which is splined a4 bevel gear 13 inV mesh with a bevel gear 14 on a shft 15 which is mounted in a case .16. Case 16 contains two trains of gears, one constituted by gear 17 fixed to shaft 15 and ars 18 and 19 freely rotatable1 respective y on shafts 20 and 21 which are also mounted in said case. The other of said trains of gears is constituted by gear 22 also fxedly mounted on shaft 15, gears 23 and 24 freely rotatable on said shafts 20 and 21 respectively, and gears 25 and 26 intermeshin with land intermediate saidA gear 22 and sai gears`23 and 24 respectively. Gears 25 and`26-therefore drive gears 23 and 24 respectively in the opposite direction to the direction of rotation of gears 18 and 19 respectively.

Also mounted on shaft 20, in the form shown is a double-ended clutch 27, keyed t0 said shaft and adapted to engage coacting clutch elements on the gears 18 and 23 by movement in opposite irections from its neutral or non-operative osition. The shi per sleeve of said clutc is engaged and) actuated by a tyoke 28 carried by the vertical rotative ro 29. By the operation of said clutch to engage the coacting clutch elements on either gear 18 or` gear 23, shaft 2O will be rotated in the one direction or the other.

Mounted on shaft 21, in the construction illustrated, isa double-ended clutch 30 keyed to said shaft and adapted to engage coacting clutch elements on the gears 19 and 24 by movement in opposite directions from its neutral or non-o rative position. The shipper sleeve of c utch 30 is engaged and actuated by a bell crank yoke 31 adapted to be o erated by the vertically movable rod 32. y the operation of clutch 30 to engage the coacting clutch elements on either gear 19 or gear 24, shaft 21 will be rotated in the one direction or the other.

Trains of gearing 33 and 34, shown in dotted lines in Fig. 9, transmit the movement of shafts 20 and 21, respectively, to feed rod 10 and feed screw 3, respectively. Such trains of gearing may be of any suitable construction such,'for example, as disclosed and claimed in my application Serial No. 201,246 filed November 10, 1917.

A third double-ended clutch 35 is mounted within the feed box 11, in the construction illustrated, and by movement in opposite directions from its neutral or non-operative position is adapted to clutch coacting gear elements in the drive mechanism, said gear elements preferably rotating in opposite directions and at different speeds, to respectively cause the slow or rapid rotation of shaft 12 to in turn cause the feed or rapid traverse movements of the feed screw 3 and the feed rod 10. The shipper sleeve of said clutch 35 is engaged and actuated by a yoke 36, mounted upon a vertical rotative rod 37.

The single control device of the present invention 1s emyllofyed, in the form shown, for selectively s i ting the shipper sleeves of Said respective clutches 27, 3() and 35 in either direction, said control device in its referred embodiment being constructed as ollows: Secured to the lower edge of the cross-rail 1 is a case 38 within which is inclosed or carried the main o erativev elements of the control device. he rimary element of said device comprises a ever 39 suitably mounted for universal movement. In the form Shown, said lever is provided at its fulcrum with a globular enlargement 40, and mounted within the case 38 are a seatplate 41 'and a friction or compression plate 42, suitably recessed to conform to the s herical surface of said enlargement 40.

at plate 41 is mounted ixedly in dposition, while plate 42 is yieldably retaine in contact with enlargement 46 by means of springs 43 carried by pins 44, which pins are suitably attached to a follower plate 45 at one end and rovided at their opposite ends with heads etween which and a wall .of the case 38 the respective springs are retained. Plate 42 is thus yieldabl retained in contact with the spherical en argement 40, exerting a pressure thereon which causes the portions o the universal joint thus provided to'be always in firm contact, and preventing said joint from becoming loose or operating too freely.

Rotatively mounted in the rear of said case 38 is an element consisting of a short shaft 46 reduced at its outer end and extending through the rear wall of said case, the opposite end of said shaft carrying a head 47 in which is provided a pair of crossslots or grooves 48, shown as intersecting at right-angles. Mounted upon the outer and reduced end of shaft 44 is a crank 49, to which is pivoted one end of a reachrod 50, the other end of which rod is attached to a crank 51 carried by a sleeve 52 which is splined to rod 37. Sleeve 52 may be maintained in operative position in any suitable way, as by a bracket 53 suitably carried by the cross-rail 1.

The inner end of lever 39 is provided With a spherical enlargement 54, which is designed to coperate with the slots or grooves 48 in the aforesaid head 47. To maintain said lever in its neutral position with enlargement 54 at the intersection of the slots 48, said enlargement may be provided with a depression 55, and a spring-pressed pin 56 for engagement in said depression may be mounted axially in shaft 46 with its inner end pro'ecting into the slots 48 at the intersection o the same. Also, to maintain crank 49 at either limit of its movement, the same may, if desired, be provided with a spring-pressed ball 57y adapted `to engage a pair of suitably positioned depressions 58 in the 'rear face of case 38.

Also carried within the case 38 is a plata 59 mounted for rectilinear movement` on a pair of horizontal rods 60 and 61, and a vertically movable plate 62 mounted upon vertical rods 63 and 64 for rectilinear movement, said plate 62 being shown as operatively attached to one of said latter rods, as rod 64, to cause the vertical movement of this rod as said plate is moved vertically on the other rod. Plates 59 and 62 are mounted` one in the rear of the other, and are designed to be selectively operated by m-ovement of lever 39. To this end, plate 59 is provided with a vertically elongated opening 65 from the vertical ed es of which a pair of inwardly extendin ugs 66 project to a position to closely em race the sides of lever 39, and plate 62 is provided with a horizontally elongated opening 67, from the horizontal ed es of which a pair of inwardly exten mg lugs 68 project to a position to closely embrace the upper and lower faces of lever 39. By reason of the lugs 66 and 68 and the direction of extension of openings 65 and 67, plates 59 and 62 are respectively moved by the lever 39 only in horizontal and vertical directions.

Plate 59, in the form shown, is operatively connected to rod 29 by means of link 69 and crank 70 and rod 64 is operatively connected to rod 32 by lever 71. Therefore, with this arrangement, horizontal movements of plate 59 are transmitted to clutch 27, and vertical movements of plate 62 are transmitted to clutch 30.

Plate 59 is also preferably provided with `a pair of slots or grooves 72 intersecting at right angles, as shown in *FigIr 3. and p ate 62 is provided with a pin 73 designed to travel in said slots 72, and to be at the intersection of said slots when plates 59 and 62 are in their neutral or central position, as shown in Fig. 2, with lever 39 in operative relation to both pairs of lugs 66 and 68.

The face of case 38 is shown as so constructed as to provide a guide and index plate 74 through which the lever 39 eX- tends. lin the form shown in Fig. 10, said index plate is provided with a pair of vertical radially-extending `slots 75, and a pair of horizontal radially-extendingd slots 7 6, each of said slots 75 and 76 being provided at its outer extremit with a transverse slot 77 extending upon either side thereof. The face of index plate 74 may be provided with suitable characters to indicate the functions which will be obtained by movement of lever 39 to the various ositions to which it may be moved within the slots 75, 76 and 77.

Uperation: Assume that lever 39 is in its central orneutral position, with the outer end thereof at the intersection of the slots 7 5 and 76 in plate 74, and with its inner end at the intersection of the slots 48 in head 47. Lever 39 will be maintained in this position by the engagement of pin 56 in de pression 55 in the spherical enlargement 54 on the inner end of said lever. In this osition of lever 39, all of the clutches 2 30 and are in neutral or non-operative position, with their end faces out of operative engagement with the coacting clutch elements on gears 18 and 23, 19 and 24, and the slow and fast driving elements Within feed box ll. If, now, lever 39 be moved to position A or osition B in' slot 76, a lug 66 on plate 59 will be engaged by said lever and said late will be shifted on its rods 60 and 61. Iovementof plate 59 is transmitted through link 69, crank 70, vertical rod 29 and yoke 28 to clutch 27, to shift the same into operative engagement with the face of the coacting clutch element on gear 18 or gear 23, as the case may be. Simultaneously with the movement of plate 59 by lever 39, the inner end of said lever will move in the horizontal groove 48 in head 47, but without actuation of said head. Furthermore, upon movement of plate 59 horizontally, in 73 will move from the intersection of s ots 73 into the horizontal of said slots, interlocking the plates 59 and 62, and thereby preventing vertical movement of the latter. The horizontal elongation of opening 67 permits the said horizontal movement of lever 39 without interference, while, as soon as lever 39 moves from its central position, itis out of operative relation to lugs 68 on plate 62, and can thereafter be moved vertically in either direction, within the limits provided by the vertical extent of opening 67, without operating said plate 62. Such vertical movements of lever 39 are ermitted at the outward limit of the horizontal movement of said lever by' the corresponding transverse slot 77. Movement of lever 39 in the latter slot in either direction causes a rotation of head 47, owing to the engagement of enlargement 54 with the walls of the horizontal slot 48. Rotationof head 47 is transmitted through shaft 46 to' crank 49, and thence through reach-rod 50 and crank 51 to sleeve 52, whereby rod 37 is rotated to shift clutch 35 into en agement with the coacting clutch element o either the slow or the fast driving gear of the feed mechanism as lever 39 is moved in the one direction or the other in slot 77 from slot 76.

Similarly, by movement of lever 39 in the opposite dlrection in slot 76, plate 59 will be slid in the opposite direction to cause a shift of clutch 27 in the opposite direction and therefore a reversal in the direction of rotation of feed rod 10, clutch; 35 bein thereafter actuated by movement of sai lever in the corresponding transverse slot 77.

If lever 39 be moved vertically to position C or to position D, plate 62 wlll be moved vertically in the corresponding direction, pin73 engaging in the vertical slot 72 and preventing horizontal movement of plate 59.

imultaneously lever 39 will move out of operative relation to lugs 66, and at the ex tremity of its vertical movement may be moved horizontally in either direction, owing to the shape of opening 65. Vertical movement r of the plate 62 is transmitted through rod 64 to lever 71, rod 32 and yoke 31, to shift clutch 30 in the one direction or the other into operative engagement with the coacting clutch element on gear 19 or gear 24, as the case may be. As above explained with relation to the movement of lever 39 vertically in transverse slots 77 at positions A or Bra similar movement of said lever horizontally in the corresponding transverse slots 77 at positions C or D will cause a rotation of the head 47 owing to the engagement in slot 48 of enlargen ent 54, which enlargement is now in one er the vertical slots in said head, together with a resultant actuation of clutch 35 in the one direction or the other as lever 39 is moved in the one direction or the other transversely to the vertical slot 75.

It will therefore be seen that by movement of lever 39 from its central or neutral position into one or another of the slots 75 and 76 in the index plate 74, not only theclutches 27 and 30 may be selectively actuated, but also the end of the selected clutch which is brought into coacting relationship with the clutch element on the adjacent gear is selectively determined. Therefore, bv

manipulation of the one lever 39. the todi holder may be fed up or down or in or out, at the option of the operator.

Furthermore, by movement of said lever in the transverse slot 77 at any one of the Traverse respectively, the

tabasco clutch 35, while actuated non-selectively, is operated in accordance with the direction of movement of the lever in such transverse slot to selectively predetermine which end of clutch 35 shall be brought into coacting relationship with the clutch elements on the adjacent gearing to selectively determine Whether the translation of the tool holder in either direction in either of its paths shall be fast or slow, fi.. e., shall be the normal feed movement or the rapid traverse movement.

Furthermore, it will be noted that, in the arrangement shown, horizontal movements of the Saddle are obtainedby movement of the lever 39 in the horizontal slots 77 and that vertical movements of the ram are obtained by movement of the lever 39 in the vertical slots 77, since movement to a horizontal slot 77 is necessary to actuate clutch 30 in the driving train of the feed screw 3 and movement to a vertical slot 77 is necessary to actuate clutch 27 in the driving train of the feed rod 10. Thereafter clutch 35 is actuated by movement of lever 39 in the selected transverse-slot 77 to complete the driving train from the driving mechanism to the feed screw or feed rod, as the case may be. curing on index plate 74, adjacent the ro er end of each slot 77, the characters F or T, to designate Feed or Rapid direction in to be moved to secure the function is clearly indicated. Therefore, by associating the horizontal and vertical movements of the lever 39 with the horizontal and vertical movements-of the tool holder, the selection of the proper movement of said lever is greatly facilitated, and bearing this relation in mind, the operator need only note the characters F and T to quickly secure the desired direction and nature of movement of the tool-holder. By interchanging the connections between the plates 59 and 62 and the clutches 27 and 30, however, the movement of the tool-holder could be made to conform in direction to the direction of movement of the control member 39 in the radial slots 7 5 and 76.

While the illustrated embodiment of this invention has been described with considerable particularity, it is to be expressly understood that the invention is not to be restricted to such embodiment, for it is capable of receiving a variety of mechanical expressions, some of which will readily suggest themselves to those skilled in the art. Thus, Whilethe elements controlled have been shown as clutches, it is to be understood that such elements may take other equivalent forms, such for example as shiftable gears, without departing from the spirit of this invention. Again, while the positions B, C or D,

which said lever is one or the other By casting or otherwise secontrol member has been shown as mechanically connected with the elements to be controlleol` it is to be understood that it is Within the purvienT of this invention and the contemplation of the claims to embrace control mechanism wherein the control member in4 its movements operates electrical contacts or vvalves to effect the selective actuation of the controlled elements throu h electrical devices or pneumatic or hydrau ic devices.
